This equal the base * height
= 14.2 * 7.18
= 101.956 cm^2 (answer)
<u><em>Answer: =13. *The answer should be positive sign.*</em></u>
Step-by-step explanation:
This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.
do parenthesis first.
2*2=4
9+(8-4)
9+4
add left to right.
9+4=13
=13
Hope this helps!
Thanks!
Have a great day!

Given
weight of chair with person on it =2118 N
Barber applies a force of 63 N
Using pascal's law
we know pressure around both sides is equal
i.e. 
pressure=
=
=
substituting values
![\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%5E2%7D%7Br_%7Bpiston%7D%5E2%7D%5Cright%20%5D)
=
